(ZK GM8.5) Master Overhaul Kit for GM 8.5" Differential

Installed on a 2004 F-150 that was really noisy. Took care of the noise and had all of the pieces to to get the job done. Could have used a bit more of the gear marking compound though.

This is a complete kit to rebuild the pinion a d carrier on your GM 8.6 Rear End. It comes with everything from bearings, races, shims, and even marking compound for when your checking your gear mesh. I love it

Good quality

They use KOYO bearings and comes with a good assortment of shims.

Ok selection of shims. Had to order a second set of shims to get enough for my carrier. The carrier shims were just barely big enough to use behind the cups.

Ordered two kits for a couple of front Dana 60 regears. Ordered on special for $130 each which is a fantastic deal. The only complaint is the small assortment of shims. Had to combine the shims from both install kits to get a decent assortment, hopefully will have enough for the second install.The inner pinion oil slinger is massive, did not fit my Superduty D60 housing so i left it out.I had Timken setup bearings for the carrier and this kit uses Koyo which is a good bearing brand. But my final install did change alittle and my backlash went from .006" to .010" but that is not the kits fault. Just make sure to use new and same brand setup bearings as the final bearings used.

I have a gm14 bolt 4.56 factory rear end the the inside pinion bearing was to large and the race was to large.

My hubby wasn’t overly thrilled with the gasket but the other parts is what he needed!

every brg, seal, shims. good product
